My Mourning Dove Survey 2012

On May 31, I conducted my annual Mourning Dove Survey for
the US Fish and Wildlife Service. The agency keeps track of the most heavily
hunted bird species in America by sending out a network of volunteers who each
conduct one or more annual surveys, counting all the doves they see or hear on
assigned 20-mile routes that were randomly selected decades ago. This provides
a fair index of dove populations over the continent. My survey route was mostly
forested when I started doing it 25 years ago, but quite a few houses and a few
businesses have sprung up, and long stretches of dirt roads have been paved.
During the 80s, I would see from 0 to 3 cars during my entire count. Now I see
from 1-3 cars at each of my 20 stops.

This year I counted 2 doves. During the first 10 or 15
years, I averaged 0 or 1, but in recent years I’ve been finding at least one
every year. My count, at the periphery of the Mourning Dove breeding range, has
far, far fewer doves than counts further west and south. Minnesota’s new dove
hunting season hasn’t reduced the number of doves in the state, at least not as
far as my data and my personal observations can show. Overall, the population
of this popular game is clearly sustaining a hunt.

When the dove season was proposed in Minnesota, a lot of
people opposed it for a wide range of reasons. I was, and continue to be,
opposed to allowing dove hunting along the hawk migration corridor along Lake
Superior during the time American Kestrels are on the move, because doves are
so easily confused with them, both in flight and while perched on wires. Unlike
the dove population, that of kestrels has been declining.

The other element of the Minnesota dove hunt that I oppose
is allowing hunters to use lead shot. The body of data showing how harmful lead
shot is for many birds continues to mushroom. “Data” is a dry and technical
term to sum up the significant annual rise in number of eagles that are
diagnosed with lead poisoning soon after deer season begins--it doesn’t begin
to describe the agony of individual eagles losing their balance, gasping for
breath, and suffering tremors, nor the investment of money and time in the
exhausting work of rehab. Study after study even shows the harmful effects of
lead shot on Mourning Doves themselves, picking it up as grit.

When the hunt was first proposed, I talked to many hunters
who disliked the idea and would have been willing to limit it--indeed, some
were willing to reject it outright. Unfortunately, a lot of anti-hunters used
the public hearings as a platform to attack hunting in general, and hunters
legitimately felt beleaguered. The NRA has put massive amounts of time and
money into widening the divisions between hunters and non-hunters, and opposes
every single proposal to limit lead shot and bullets, even in the few areas of
the country where critically endangered birds such as condors remain and die
every year from lead poisoning tied to hunting. This dove season was brand new,
so requiring non-lead shot from the start wouldn’t have been taking away
anything from hunters and would have been an excellent way for the DNR and
people on both sides of the issue to show that they are responsive to public
input and capable of compromise. Unfortunately, the anti-hunters made the DNR
feel beleaguered, too. I found it frustrating that rabid anti-hunting took the
focus from the nuanced issues involved, and that this became yet another
polarizing issue in a world too divided already. Hearing the pleasing coos of these
beautiful birds on my survey, I was struck by the irony of this lovely bird
blending soft and muted browns with traces of black and white being used by
uncompromising people no longer capable of seeing any colors except black and
white, and no longer capable of speaking softly on any topic when yelling has
become the standard. It’s hard for any bird to symbolize peace in a world where
compromise and camaraderie have so completely vanished.

It is true that the world we live in is now being torn apart by polarizing figures. It is sad to hear that our winged friends are the ones that have to bear the brunt of our failure to compromise. It is my first time reading your blog and I am enjoying. Thanks for the post and the photos!
